To define clearances required around the BTS, cut the template out of thepacking cardboard by following the dotted line (see Figure 6).2. Find a wall area which is large enough to cover all parts of the template andplace the cardboard template on the wall at the required height. Use a spiritlevel to check that the template is in a straight position.3. Mark the fixing points on the wall for the upper screw holes of themounting rack (R1 and R2, see Figure 5). For example, use a centre punchthrough the template to mark the fixing points.4. Drill holes R1 and R2 in the wall and clean them out. Insert anchor plugs(or an appropriate counterpart, depending on the material) into the wall.5. Position the mounting rack in the correct location on the wall and attach itwith screws through holes R1 and R2 (see Figure 7). Use a spirit level toset the mounting rack straight (adjustment is possible due to the oval shapeof holes R1 and R2). Tighten the screws when the rack is level.6. Drill screw holes for the lower anchor screws through the holes marked R3and R4 in Figure 7. Insert the anchor plugs (or appropriate counterparts)into the wall.7. Position the rectangle shaped washer over screw holes R3 and R4 andinsert and tighten the screws.

Mounting the BTSDN991456 © Nokia Corporation 37 (72)Issue 3 en Nokia Proprietary and ConfidentialNoteFixing the pole brackets and the mounting rack onto a poleBefore taking the mounting rack to the pole, perform the tasks instructed in Steps1 and 2 below.1. To fix the upper pole bracket to the mounting rack, screw the M6 x 20Allen screws through holes R1 and R2 into the upper front block, as shownin Figure 10. Make sure that the front block is the correct way up (the setof three adjacent screw holes on the back of the block should be on theupper edge). Use a torque driver with a 4 mm Allen bit to tighten the screwsto 5.5 Nm (4.06 lb ft).2. To fix the lower pole bracket to the mounting rack, screw the M6 x 20Allen screws through holes R5 and R6 into the lower front block, as shownin Figure 10. Make sure that the three adjacent screw holes are on the upperedge of the block. Use a torque driver with a 4 mm Allen bit to tighten thescrews to 5.5 Nm (4.06 lb ft).3. Bring the mounting rack/pole bracket combination to the pole.4. Position the upper front block of the pole bracket on the pole. Rotate theback block so that you can insert the free bolt and square nut into the freeslot on the other side of the front block.5. Tighten the bolts in even stages to fix the upper pole bracket to the pole.Use a torque socket spanner/wrench with a 6 mm Allen bit to tighten thebolts to 12 Nm (8.85 lb ft).6. Fix the lower bracket to the pole in the same manner as the upper bracket.

One uses grooved metal bands,as described in procedure [A] below. The other type of locking device usessmooth bands and a locking rack, as described in procedure [B] below. Follow theprocedure for the type of locking device and band in your kit.[A] Pre-assembling the pole brackets and bands (grooved band type)1. Assemble the locking device and band by inserting the end of the metalband approximately 25 mm (1 in.) into the locking device. The correct setup of the parts is shown in Figure 12.Bend the surplus end of the metal band underneath the locking device, asshown in [3] [A] in Figure 12.Flatten the bent-over end of the metal band to remove any distortion.The locking device is now assembled.2.

Fix the upper pole bracket to the mounting rack by screwing the M6 x 20Allen screws through R1 and R2 into the upper front block, as shown inFigure 14. Make sure that the front block is the correct way up (the set ofthree adjacent screw holes should be on the upper edge of the bracket). Usea torque driver with a 4 mm Allen bit to tighten the screws to 5.5 Nm (4.06lb ft).2. Fix the lower pole bracket to the mounting rack by screwing the M6 x 20Allen screws through R5 and R6 into the lower block, as shown in Figure14. Make sure that the set of three adjacent screw holes is on the upper edgeof the bracket. Use a torque driver with a 4 mm Allen bit to tighten thescrews to 5.5 Nm (4.06 lb ft).3. Take the mounting rack/pole bracket combination to the pole.4. Wrap the metal band of the upper bracket around the pole.5. Insert the free end of the metal band (grooved type) into the slot on theworm screw housing, as shown in [B] of Figure 12. Wind the metal bandinto the locking device by turning the nut with a flat screwdriver or 8 mmhexagon socket and wrench.ORInsert the hook-shaped free end of the band (non-grooved type) into the sloton the worm screw housing. Tighten the worm screw using a flatscrewdriver or 8 mm hexagon socket and wrench.6.

Cabinet cablingDN991456 © Nokia Corporation 51 (72)Issue 3 en Nokia Proprietary and ConfidentialNote8Cabinet cablingThis document assumes that you are using the ready-made cables supplied byNokia, or that all cables have been prefabricated before starting the cabling of theBTS. For information on the cable types and connectors refer to Nokia MetroSiteEDGE Base Station: Requirements for Installation and Operation. For the pinconfigurations refer to Nokia MetroSite EDGE Base Station: ProductDescription.The connectors on the units’ front panels are protected with rubber caps. Removethe caps only from those connectors that will be used for BTS cabling.8.1 Preparations for cablingBefore starting the cabling, do the following:1. Displace the sealing strip around the cable entry block. See [A] in Figure16.2. Loosen and remove the two Allen screws that keep the cable entry block inplace. Use a torque driver with a 4 mm Allen bit. For the location of thescrews, see [B] in Figure 16.

The Nokia MetroSite EDGE Base Station must bepermanently wired to a disconnect device (such as a circuit breaker), inaccordance with current local and national wiring standards.The following warning applies to the AC power supply. The protectiveground wire can only be used for protective conductor installations. Usingthe protective ground conductor for other purpose is dangerous to life.Ensure that the ground connection is established before the power outlet isconnected to the BTS.The mains power supply must be switched OFF before starting installationof the power supply cable!

Make sure that the site’s mains power supply is switched OFF and that theswitch on the power supply unit is in the stand-by position.2. Open the connector shield by loosening the retaining screws with a torquedriver and a T10 Torx bit (see Figure 19).3. Open up the rubber sealing piece and route the power supply cable throughit. Close the sealing piece.DC power can be fed in with three separate conductors. In this case, reverse therubber sealing piece so that the three small recesses are facing each other andform three small holes (see Figure 19). Use the three holes for routing theconductor cables.4.
